Gastroscopy is a medical procedure that allows gastroenterologists to examine the inside of the esophagus, stomach, and the first part of the small intestine (duodenum). Using an endoscope, a thin, flexible tube with a camera at its tip, doctors can diagnose and, in some cases, treat conditions of the upper digestive tract.
A gastroscopy is a diagnostic test performed to identify problems in the upper parts of the digestive system. It is useful for evaluating symptoms such as abdominal pain, nausea, vomiting, difficulty swallowing, or gastrointestinal bleeding.
It is common for the patient to be asked to fast for several hours before the procedure.
During a gastroscopy, the doctor can see signs of inflammation, ulcers, tumours, or infections.
The duration of a gastroscopy varies depending on the complexity of the case and whether biopsies are taken during the procedure. In general, a standard gastroscopy takes between 15 and 30 minutes.
A biopsy can be performed during a gastroscopy to obtain tissue samples that will be analyzed later.
